Recall that two figures are similar if their corresponding angles have the same measure.
Therefore, if we reduce or increment the measurement of each angle, the resulting figure will not be similar to the original figure.
Now, notice that increasing the length of the sides of a polygon does not necessarily result in a similar figure, for example:
Now, recall that translations, rotations, reflections, and dilations result in similar figures.

The slope of the wooden beam is 39.8 ft
STEP - BY -STEP EXPLANATION
What to find?
The slope of the wooden beam.
Let y be the slope length.
To determine the slope length of the wooden beam we will follow the steps below.
Step 1
Write down the formula in calculating the sloping beam.
rise² + run² = slope length²
Step 2
Observe from the given diagram;
The value of the rise =12
The value of the run =76/2 = 38
Step 3
Substitute the values into the formula.
12²+ 38² = y²
Step 4
Simplify the above.
144 + 1444 = y²
1588 = y²
Step 5
Take the square root of both-side of the equation.
y = 39.8 ft
Therefore, the length of the sloping beam is 39.8 ft

1.175
First find the closest values possible to 0.88 (88%) on the z-score table. Once found we can see that it is located at positive 1.1 and directly in-between .07 and .08. Therefore we take the half of the two, .075, and get the answer of 1.175. The positive z-score, 1.175, tells us that we are 1.175 standard deviations above the mean.
Second find the closest values possible to 0.12 (12%) on the z-score table. We find it at -1.1 and perfectly in-between .07 and .08. We repeat the same steps as before and get -1.175. The negative z-score, -1.175, tells us the we are 1.175 standard deviations below the mean.

represent the cost of each field trip,
For what number of students will the total cost of each field trip be the same,
and what will that cost be?
O A. 120 students: $10
O B. 2 students: $40
O G. 40 students: $2
OD. 10 students: $120
Need help fast
Answers
Method 1
Write an equation for the total cost for each trip.
The history museum
Let the number of students = n
Total cost = 10 + 15n
The aquarium
Let the number of students = n
Total cost = 20 + 10n
Next, equate the two equations to find what number of students will the total cost of each field trip be the same.
[tex]\begin{gathered} 10\text{ + 15n = 20 + 10n} \\ 15n\text{ - 10n = 20 - 10} \\ 5n\text{ = 10} \\ n\text{ = }\frac{10}{5} \\ n\text{ = 2} \end{gathered}[/tex]The number of students = 2
The cost = 20 + 10(2) = 20 + 20 = $40
Answer
2 studnets; $40
Method 2:
To find number of students will the total cost of each field trip be the same.
From the graph, look for the point where the two graphs intercept.

You deposit $3000 each year into an account earning 8% interest compounded annually. How much will youhave in the account in 20 years?
Answers
The rule of the compounded interest is
[tex]A=P\frac{\lbrack(1+\frac{r}{n})^{nt}-1\rbrack}{\frac{r}{n}}[/tex]A is the final amount
P is the amount each year
r is the interest rate in decimal
t is the time
n is the number of periods per year
Since you deposit $3000 each year, then
P = 3000
Since the annual rate is 8%, then
r = 8/100 = 0.08
n = 1
Since the time is 20 years, then
t = 20
Substitute them in the rule above to find A
[tex]\begin{gathered} A=\frac{3000\lbrack(1+\frac{0.08}{1})^{1(20)}-1\rbrack}{\frac{0.08}{1}} \\ A=\frac{3000\lbrack(1.08)^{20}-1\rbrack}{0.08} \\ A=137285.8929 \end{gathered}[/tex]You will earn $137 285.8929 after 20 years

Jacqueline took out a personal line of credit in her senior year of college with an annual simple interest rate of 4%.she takes 51 months to pay off the loan in full and pays 1530 in interest. A. How much was the original line of credit amount.B. How much did Jacqueline pay in total.
Answers
Given data:
The given annual interest is r=4%.
The given time is t=51 months= 4 year+3 months=4.25 years.
The interest ammount is i=1530.
A)
The expression for the simple innterest is,
i=(Prt)/100
Substitute the given values in the above expression.
1530=P(4)(4.25)/100
P=9000.
Thus, the original amount credit is 9000.
B)
The expression for the total amount is,
A=P+i
Substitute the above calculated values.
A=9000+1530
=10530
Thus, the total amount is 10530.
Chloe makes flapjacks.
A pack of flapjacks costs Chloe 60p to make.
She sells the flapjacks for a profit of 30%.
For how much does Chloe sell a pack of flapjacks?
Answers
Answer: 78p
Step-by-step explanation:
If she sells them with a profit of 30%, this means she is getting 30% more than they cost to make. They cost 60p, so we will set up an equation. Don't forget that a percent divided by 100 becomes a decimal.
60p * 130% = 60p * 1.3 = 78p
(30/100)*60 = (30*60)/100 = 18
